STERE'OTYPE-PLATE CASTIN'G-BOX-COOLING- APPARATUS.

- To all whom it may concern:

- means for cooling boxesfor castingv stereotype plates and the like, and is particularly intended for use in connection with the boxes of the type shown in my Patent No.

945,678, dated January 4, 1910, 'which boxes have-a tiltable core that is subjected to great heat, as all the plates are; cast around such core. It is the object. of the present'invention to keep the core or box at a sufficiently high temperature to prevent injury to the'plates while being cast, and also to prevent the core or box becoming overheated and injured thereby.

The present invention is theresult of a series of experiments I have made with such boxes in efforts to obtain the desired objects and by the present invention I have realized such object by simple and efficient means, and the plates can be cast very rapidly in such boxes without overheating the box, and without injuring the plates during the casting thereof. 7

The accompanying drawings illustrate diagrammatically one practlcal embodiment of the invention and the following description thereof, together with the drawings, will enable others skilled in the art to adopt and use the same; and in the claims the essential features of the inven tion for which protection is desired are summarized.

through the casting box. r

The casting box may be of any suitable construction to cast plates of any desired kind, but I have illustrated a box forcasting tubular stereotype plates, lsuch box having a drag l, cope 1 and a core 1 substantially as described in my aforesaid patent. v 1

The core 1 is adapted to be inclosed be tween the cope and drag as indicated in Fig. 4, and in'the annular space between the outer surface of the core and the inner surface of the cope and drag a tubular plate may be cast.

The core is preferably tiltably mounted.

on trunnions 1 journaled in suitablebearings in the base frame 5, and after a plate is cast the drag may be opened and the core tilted, as indicated, in dotted lines in Fig. 3, to enable the cast plate to be readily removed therefrom. V

The core. is hollow, and within the core are arranged two conduits or pipes 2 and 3 which respectively connect with passages 2 and 3 in the opposite trunnions 1 Preferably the pipes 2 and 3 are parallel and of equal length and extend to, or near to, the top of the chamber in the core 1", so that the water or other fluid which is admitted into said core as hereinafter described will enter the core adjacent the top end or head thereof, whichhead is subjected to the greatest heat, as the metal is poured into the box at the head of the core. I

Adjacent the casting box are two. reservoirs or tanks 2 and 3 which contain water or other suitable cooling fluid, and which tanks are preferably arranged at different levels, and may be supported by any con- The water passage 2 in the core is connected by suitable pipe connections 2", 2, and 2, with the lower end of tank 2. r

The water passage 3 is connected by suitable pipe connections 3*, 3 and 3 with the tank 3 The tanks 2 and 5 are provided with water gages, g, g respectively; and also with vent pipes 2 and 3 respectively, at their upper ends.

7 The tanks may be supplied with water "by means of pipes 4 and 4* respectively which may be provided with valves 4' and 4, which are normally-closed.

The proper fluid supply may be maintainedrin the tanks by observing thegages "g, {the fluid "being supplied through the "cause the-tanks are alb'ovethe top of-the core whenfthe casting box is in closed position;

The core remains practically full of hot fluid "or water, and when the latter rises above -"a 'certain -tenrperature or develops steam therewtll be rush of fluid from'the corebaclr into one or the other oat the tanks '2 or 3 sometimesinto both; and when any overheated fluid or steamisthus forced back *or mit of the 'core,' itsplace is immediately su pplie'd by fluid frommne or' from both, of the tanks. V

lhave observed that the level of fluid in the -t'anks does not: always remain uniform it will sometimes 5 rise the upper tank and then recede and at the sametime the fluid in the' lower tank may rece'de whenthat in the uppertan'k rises. sometimes theactions will bereversed. The fluid does not-seem to have any specific-control 'over itself when confined in the ho1low membenof the castin'g box, and Whenheated it mayepass backthrou'gh either 1 or "both of'*th'e pipe connections ito either or tether-ste When using the ?'type for box used in my sa'i'd patent, ithe movement of flu-id to I and from the core is facilitated- :or assisted by 'the itiltingf movements of the 'core -fromithe'iverf tical ip'ositioniassumed :for casting a'rplate, to the horizontal, or substantially horizontal :p'ositi'on, assumed fori'removal of a east plate from the core.
